Abstract (en)
[origin: WO2009040732A1] An apparatus for observing the appearance of a surface (2) of a sample (1) of semitransparent material, the apparatus comprising a light source (11) for illuminating at least a region of interest (16) of the surface of the sample (1) from a predetermined direction and means (14) for observing a response to the illumination of the region of interest (16), wherein the illuminated region (5) comprises the region of interest (16) and a region surrounding the region of interest (16). In this way the influence of emitted scattered light (32) on the accuracy of the observation of the appearance of the sample (1) is minimized.
